From the #1 New York Times bestselling author of the Percy Jackson and the Olympians series

A triple-crown winner of mystery’s most coveted awards, Rick Riordan brings his Texas-style take on the crime thriller to an island paradise where ex-P.I. Tres Navarre finds himself stranded with a killer as unstoppable as a force of nature.

Tres Navarre and his new wife Maia came to celebrate their honeymoon. But no sooner had they arrived on Rebel Island than a reminder of Navarre’s past showed up dead in room 12. Suddenly Tres finds himself flashing back to the grim childhood summer that changed his life. When a second corpse turns up, it’s clear that the past isn’t dead and buried—yet. What dark secrets were kept that long-ago summer and who is back to avenge them? These are questions Tres must answer as a monster hurricane hits, trapping them on a flooding island, and as the hotel’s remaining guests are being brutally murdered. Tres knows better than anyone the dangerous line between vengeance and justice—and this time he may have to cross it.
